1, 3, 4, 6, 11, 13 GND Ground. Solder these pins to a low impedance ground plane. to 16, 18, 22 2 RX_OUT Receive Path Output. This pin is dc-coupled to ground and ac matched to 50 Ω. 5 TX_IN Transmit Path Input. This pin is dc-coupled to ground and ac matched to 50 Ω. 7 VGG_PA Power Amplifier Gate Bias. This pin is used to set the desired quiescent current of the amplifier. 8 VDD_PA Power Amplifier Drain Bias Voltage. 9, 10 NIC No Internal Connection. Solder these pins to a low impedance ground plane. 12 CPLR_OUT Transmit Path Coupled Port. This port is used in connection with a detector to monitor transmitted power. 17 ANT RF Common Port. This pin is dc-coupled to 0 V and ac matched to 50 Ω. 19 VDD_SW SPDT Switch Positive Bias Voltage. 20 CTRL_SW Switch Digital Control. This pin controls the state of the SPDT switch. 21 VSS_SW SPDT Switch Negative Bias Voltage. 23 VGG_LNA LNA Gate Voltage Bias. This pin is used to set the desired quiescent current of the LNA. If this pin is supplied with 0 V or is connected to ground, the LNA runs in self bias mode at a typical current of 80 mA. 24 VDD_LNA LNA Drain Voltage Bias. EPAD Exposed Pad.
